说明

一般說明

Sodium tetraphenylborate (Ph₄BNa) undergoes rhodium-catalyzed addition reactions with N-phenylsulfonyl aldimines to afford R(Ph)CHNHSO₂Ph.

應用

Sodium tetraphenylborate (Ph₄BNa) may be used in the synthesis of polyfunctional biaryls via modified Suzuki cross-coupling reaction. It may be employed as a derivatization reagent for the analysis of methylmercury and ethylmercury by gas chromatography (GC) coupled with atomic fluorescence spectrometry (AFS), microwave-induced plasma atomic emission spectrometry (AES) and mass spectrometry (MS).

其他說明

用于钾的沉淀和滴定；用于胺、季铵化合物和钾的电流滴定；用于季铵盐表面活性剂的滴定；存在钾选择性电极时，用作胺和 NH₄Cl 的滴定剂
